Use StringRef::substr() and unbounded StringRef::compare() instead of bounded version of StringRef::compare() because bounded version of StringRef::compare() is going to be removed.

Eliminates an assert in the strncpy/strncat checker caused by not validating a cast was successful. If the value of an argument was unknown, the cast would result in a NULL pointer which was later being dereferenced.

This fixes Bugzilla #9806 .

This patch adds modeling of strcmp() to the CString checker. Validates inputs are not NULL and are real C strings, then does the comparison and binds the proper return value. Unit tests included.

strcat() and strncat() model additions to CStringChecker.
...
Validates inputs are not NULL, checks for overlapping strings, concatenates the strings checking for buffer overflow, sets the length of the destination string to the sum of the s1 length and the s2 length, binds the return value to the s1 value.

Adding Static Analyzer checker for mempcpy().
...
Models mempcpy() so that if length is NULL the destination pointer is returned. Otherwise, the source and destination are confirmed not to be NULL and not overlapping. Finally the copy is validated to not cause a buffer overrun and the return value is bound to the address of the byte after the last byte copied.

[analyzer] Use the new registration mechanism on some of the experimental checks. These are:
...
CStringChecker
ChrootChecker
MallocChecker
PthreadLockChecker
StreamChecker
UnreachableCodeChecker
MallocChecker creates implicit dependencies between checkers and needs to be handled differently.

Rename the 'EntoSA' directories to 'StaticAnalyzer'.
Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).
